Feature Schlumberger Drilling Technology Used to Enable Geothermal Heating Solution in Europe
Multilateral well design is the first of its kind for a geothermal application in France.
High build rate rotary steerable system
The PowerDrive Archer RSS delivers complex 3D well profiles while maintaining high ROP and wellbore quality. It minimizes well profile restriction and optimizes attack angle in troublesome formations. The system enables operators to maximize reservoir exposure, increasing hydrocarbon production potential. Increased DLS capability gives control in unconsolidated formations.
Additional advantages of the PowerDrive Archer RSS include the ability to drill complex curves and trajectories and perform openhole sidetracks at any point without requiring a trip out of the hole. It can kick off deeper and land early in the reservoir, maximizing ROP for optimal performance in the vertical section and reducing risk of mechanical sticking while improving wellbore quality. Fast, reliable directional openhole sidetracks can be completed to reduce time spent drilling multilateral wells and enable wells to be placed exactly where required.
The PowerDrive Archer RSS produces smooth, high-quality wellbores, reducing stick/slip, torque, and drag as well as making it easier to run casing and wireline logs for trouble-free well completions. Its moving components are internal; its internal pads push against an articulated sleeve pivoted on a universal joint to offset the steering unit from the tools’ axis. This creates a hybrid effect that drives the bit, delivering well profiles previously only possible with motors.
Through finite element analysis modeling and bending moment analysis on the PowerDrive Archer BHA, a predicted fatigue life for BHA components was produced for aggressive build rates. The PERFORM Toolkit data optimization and analysis software automatically performs this complex fatigue management and enables real-time monitoring in the field.
